The best way to five students from a list of 626 students available such that it exhibits a random process is to List each name on a separate piece of paper; place them all in a hat, and pick five.

The selection process which should be undertaken by the student government, should be one which is inclusive and representative. Hence, the five students to be selected which makes up the sample of the total student should be chosen at random and transparently.

Hence, listing the names of each student on a Seperate piece of paper, placing it in a hat and making 5 selections showcase randomness and transparency, hence, it should be the adopted selection process.

Given the parent function f(x) = 8x + 9, rewrite the function after the following transformation: reflect over the x-axis. Group
kari74 [83]

Given:

The parent function is

f(x)=8x+9

To find:

The function after the reflection over the x-axis.

Solution:

We know that, if a function f(x) reflected over x-axis to get the function g(x), then

g(x)=-f(x)

Putting f(x)=8x+9, we get

g(x)=-(8x+9)

g(x)=-8x-9

The function after the reflection over the x-axis is g(x)=-8x-9.

Therefore, the correct option is B.

Three students failed their last test. If 12% of the class failed, how many students are in the class?
stellarik [79]

Answer:

There are 25 students in the class.

Step-by-step explanation:

Let x be the number of students in the class

12% failed and the number of students is 3

x*12% = 3

x*.12 = 3

Divide each side by .12

x * .12 /.12 = 3/.12

x =25

There are 25 students in the class

cake batter poured into a pan creates a circular batter pattern whose radius increases at a constant rate of 1 in/sec. at what r
docker41 [41]

Answer:

8 π .

Step-by-step explanation:

radius increases at a constant rate of 1 in/sec.

dr / dt = 1

where r is radius .

radius after 4 sec

r = 1 x 4 = 4 in

area A = π r²

differentiating both sides

dA / dt = 2 π r dr / dt

Putting dr / dt  = 1 , r = 4 in

dA / dt = 2 π x 4 x 1

= 8 π sq in per sec.

Area increases at the rate of 8 π per sec.
